This is a y-chromosome DNA project. Only men are eligible to join. The Northridge surname arose in England when surnames came into use and where many families remain. We would like to know more about English family members. The Northridge family in Co. Cork, Ireland is documented in that country from the late 1600s and yDNA has shown these Northridges share a common ancestor. Are they related to the Northridges in England? Might they have migrated from England? Broad yDNA testing would help us answer this question. Family members migrated from both England and Ireland to the United States, Australia, and Canada. We encourage broad participation of male, direct line Northridges, Northedges, Nortridges, and Norris (who were formerly Northridge) in our yDNA surname project to learn more about the different family branches in all locations and their inter-relationships. Genealogical research has succeeded in clarifying who some of these families are and in unearthing family stories. Where records have been lost, we hope that yDNA can help us to identify linkages within this family and enable sharing of family information.
